The “singing” Tesla coil, also known as a musical Tesla coil, is a fascinating application of Tesla coil technology that combines the dramatic visual display of electrical discharges (the “lightning bolts”) with sound production. Here’s how it works: Tesla Coil BasicsA Tesla coil is an electrical resonantalerate electrical discharge on the torm ofarcs or ‘lightning bolts* which occur when the electric field generated by the coil becomes strong enough to ionize the air, allowing electricity to fl
